Stabilisers UPS Transformers, are all rated in VA or KVA,to state how much current times its voltage should be consumed.What it means is while a device(non-resistive) is connected and draws 1 amp at 100volts the WATTAGE is 100 ,but being non-resistive there is some reactive current, which is wasted-the amount depends on the power factor of the cct.Wattage =VxA xpf. If pf= 0.9 VA=100/0.9=111 VA.Originally posted by skarthikeyan94@Jan 16 2006, 12:46 PM
Why the capacities of stabilizers and UPS are quoted in VA and kVA?
What is the relation between VA and watt?
